What is different on the X1 version compared to the old iZi Go Modular i-Size?

The BeSafe iZi Go Modular X1 i-Size differs from the previous version in 3 aspects: 1. It has a changed headrest area design which offers more internal space for the growing baby and does not require removing cushions anymore. 2. It features a different kind of baby cushion, the BeSafe Newborn Hugger™. This Newborn Hugger™ gives the baby more side support and stability while also featuring a wedge that lifts the baby's back instead of bottom for a flatter sitting angle. 3. Instead of soft foam, it features the Dynamic Force Absorber™ in the side wings of the seat shell for an optimized protection of the head area.
